Why do Transformers aliens speak with spoken words & hand gestures?

If anyone needs a course in the Idiotic Internet of Things (IdIoT), it’s them Autobots and Decepticons!

In the 80s, Doordarshan used to have Star Trek on Sundays. Although I like it very much then, I vaguely remember it now. I do remember my mother’s skepticism about the serial’s premise. How come every planet they go to, the inhabitant species speak in English (with a distinct American accent, I might add)?

As per the TV serial Big Bang Theory, geeks of all ages in America are addicted to comic book characters such as Transformers and Star Trek. I have attempted to watch these movies several times but they couldn’t hold my attention even once.

Whether it is Autobots or Decepticons, all Transformers aliens speak with hand gestures and spoken words.

Whether it is Autobots or Decepticons, all Transformers aliens speak with hand gestures and spoken words, even when they talk among themselves.
